2, apparently 2-flowered. Peduncle up to the raceme fili¬ 
form, shorter than or surpassing the leaf, with a small tubu¬ 
lar sheath in the middle. Sepals abruptly long caudate, 
3-nerved. Lateral sepals exceeding 11.2 mm. long (tails in¬ 
complete), connate into an ovate deeply bidentate lamina 
which is 7.5 mm. wide near the base, obliquely 6-nerved, 
the 2 inner nerves extending to the tip of the tails, dorsally 
carinate. Dorsal sepal triangular-ovate, 11.2 mm. long 
including the tail which is about 6.8 mm. long, 5.2 mm. wide 
near the base, mid-nerve dorsally carinate. Petals minute, 
obliquely obovate-quadrate, 1 mm. long and about equally 
wide at the broadly rounded apex, the entire center oc¬ 
cupied by a fleshy pyramidal callus. Labellum trifid; lateral 
lobes relatively large, obliquely triangular in outline, 1.9 mm. 
long measuring along the inner margin, 1 mm. wide along 
the spreading truncate base, acuminate, the outer margin 
irregularly sinuate-bilobed with the anterior lobe slightly 
indented, the inner margin straight at the base then abruptly 
and irregularly concave, the basal part with a transverse 
flabellate thickening; middle lobe very minute, linear-trian¬ 
gular. Column small, shorter than the petals. Anther quad¬ 
rate-ellipsoid, with 2 spreading triangular tips, 2-celled. 
Pollinia 2, oblong-pyriform. 
This description was made from herbarium specimens. 
Lepanthes guanacastensis closely resembles L. Johnsonii 
Ames vegetatively, but it has very different petals and lip. 
It is remarkable for its thick fleshy roots, its stout callose 
petals and the peculiar side lobes of its lip. Because 
of these peculiarities, L. guanacastensis appears to have no 
allies.
